I, like you, have a number of reservations that have been cancelled at Conrad Manila. I have more going out through May that remain, for now.
Due to the lockdown, Conrad Manila currently is not accepting guests, whether walk-in or with current reservations (which have been cancelled).
All restaurants are closed and any open space (pool, garden, balconies etc) are closed and not accessible. Food is being supplied to the handful of guests who are trapped, via room service (with limited menu) only.
